What does an offical UDRP notification look like?

Question

I have a modest number of .com/.net/.org domains. They all have correct contact information on the WHOIS, but the email address gets an awful lot of rubbish sent to it. I have also been sent official looking documents through the post but those turned out to be scams.

If someone does decide to file an offical UDRP claim against one of my domains, or any other offical non-scam notifications, how would I be notified? How could I know it's real?

Many thanks.
